SANITARY DENTAL WASTERECEPTACLE.

Specification of Letters Patent. Application filed June 19, 1909. Serialno. 503,079.

Patented Apr. 2, 1912.

I To all whom 'it may concern:

Be it: known that I, THoMAs S. HARLAN, a citizen of the United States ofAmerica, and resident of Salt Lake City, Salt Lake county,

Utah, have invented a certain new and usethe said cup holder beingprovided with a swiveled support adapted to be fastened to the underside of acabinet or table, whereby the receptacle .can be swung out ofsight beneath the cabinet or table, as will heremafter more fullyappear.

In the accompanying drawings-Figure 1 is a perspective of a sanitarydental waste receptacle, embodying "the principles of my invention,showing the same attached to the under side of the corner of adentalcabinet. Fig. 2 is an enlarged plan view of the receptacle shown inFi 1. Fig. 3 is a vertical 'volve about a vertical axis.

sectional view on line 3--3 in Fig. 2.

Asthus illustrated, my invention com.- prises an L-shaped arm A providedat its upper end with a reduced end portion a and at its lower and righthand end with an upstanding threaded portion a'. A bracket bearing B isprovided with holes 6, whereby the same can'be attached to the underside of the cabinet X, said bracket bearing being also provided with avertical bore or openingb adapted to receive the stem a of the arm. Thetop of the bracket bearing B has a depression or seat b, in which isdisposed a washer b the upper end of the stem a being riveted overtohold the said washer thereon. Inthis W l y a swivel connection ispz-ovided between the arm A and the bracket aring 13, whereby the arm isadapted to re- The cup C is provided with annular side walls. and with ahead or rib 0 extending circumferentially' thereof, located somedistance above the bottom thereof. An annular cup-holder D is alsoprovided, the perimeter d thereof being rounded and curled over toprovideedges (2' that engage immediately below the bead or rib c, asshown. Thus the cup is supported by contact therewith at some distanceabove its bottom or lower edge, and does not contact with the bottomofthe cup-holder. The said cup-holder is provided with a centrallydisposed and downwardly projecting boss d provided with a threaded boreor opening adapted to receive the threaded stud a on the swinging orswiveled arm. In this way the cup is removable from the cup-holder, andthe cup-holder is removable from the L-shaped swiveled arm by which itis carried. As a matter of further and special improvement, the said cupmay have a portion of the interior thereof provided with a series ofteeth E, disposed near the perimeter or upper edge of the cup, wherebycotton or waste may be readily dislodged from the dental instrument. Byplacing the instrument between two of the teeth, and then drawing theinstrument upward, the cotton or waste or other material on the lowerend of the instrument will be completely dislodged or removed therefrom.

From the foregoing, it will be seen that the advantages of my inventionare as follows: It is sanitary, because it can be emptied and sterilizedafter each patient, or at any time, without consuming more than amoments time. of sight of the patient at all times. and the swinging armenables the operator to swing the cup under the corner of the table, sothat the next patient taking the chair cannot see into the cup; thenwhen the patient The contents are out is seated, and the operator pullsthe table up to the patient. the cup may be pulled cup without thepatient having seen the contents thereof. It holds any and all wastefrom the dental table. The receptacle proper, being cup-shaped, holdsany and all waste, such as old burs, disks, polishing strips, ligatures,carborundum, stones, articulating paper, all sized cotton pellets andthe cotton "rolls which are being used more every day, and any size thatis used in the mouth can be put in this receptacle, and much other wastefrom the dental chair. The re.- ceptacle, being fastened to the nearestright hand corner of the table, enables the operator to dispose of wastewith, the least loss of time; and should heavy oils or coagulations ofblood cause cotton to hang to, the pliers, the operator can do this bydrawing the pliers to the right until the cotton comes in contact with aset of spurs or teeth fastened near the top and on the inside withpoints curved downward where it' space 'onthe table. The receptacle,being. placed underneath the table, is out of the Way, and occupiesspace that can be used for nothing else, leaving the table forinstruments or. other things necessary for the work. L

The receptacle, being made of steel or copper, heavily nickeled andnicely orna mented, is quite an ornament to any dental table. Being madeof heavy steel or copper, and being heavily nickeled, the. device shouldlast a lifetime,' and the cup cannot 'be knocked out of its positionunless taken hold of and lifted straight up.' The shank of thereceptacle is fastened to the frame of the table by two screws whichsecurely fasten it, and the receptacle proper can be turned aroundeasily without jarring the table or loosening anything, as it fits in asocket. The sides of the cup-holder bulge outwardly beyond the cup, thusguarding the latter against contact with other objects' that might causeits dislodgment, or'

tends to do so.

Although I have described my invention as being particularly useful inconnection with dental work, it will be understood that I do not solimit myself, and that it may be used for various purposes without inany way departing from the spiritoi my invention.

What I claim as my invention is: 1. A sanitary dental waste receptaclecomprising an 'L-shaped arm provided with a swivel at its upper end, anannular cupholder disposed upon the lower end of said lower end of thearm, and a cup removably.

disposed in said cup-holder, the latter being formed with an annularperimeter, and with sides bulging outwardly beyond the perim- .eter ofthe said cup.

3. In a device of the character disclosed,

an L-shaped arm, a swivel for the, upper endof said arm, adapted to beattached to the under side of a support, a cup-holder for the lower endof sai arm, and a cup removably disposed in said cup-holder, said cupprovided with an annular bead or rib located at a distance above thebottom thereof, and the said cup-holder being provided with an annularand inwardly projecting edge or perimeter adapted to engage the cup immediately below-said bead or rib, ,as set forth.

Signed by this 14th day of June, 1909.
